Flocculation of brewing yeast refers to its tendency to

  • A.Clump together and settle out of the beer
  • B.Ferment the last traces of sugar in the wort
  • C.Produce large amounts of carbon dioxide gas
  • D.Survive at unusually high temperatures

Answer: A

Flocculent strains aggregate and drop out once fermentation slows, which clears the beer and makes the yeast easy to recover. A strain that flocculates too early may leave the beer under-attenuated and sweeter than intended.
